A hoist mechanism 102 for loading into or unloading from a load carrying space of a vehicle. The hoist mechanism comprises a lifting arm 108 with a first free end mounted at a pivot 148 to a housing, and a second free end moving in a vertical arc 156 about the pivot when the lifting arm is moved between raised and lowered positions. A first physical stop abuts the lifting arm and prevents its movement beyond the lowered position. A variable length of cable or webbing 130 is provided with a cable stop 146 such that reducing or increasing said length of cable or webbing controls movement of the arm between lowered and raised positions, and increasing said length of cable or webbing when the lifting arm abuts the physical stop in its lowered position extends the length of cable or webbing beyond the second free end of the lifting arm. The hoist mechanism can be used to load articles, e.g. motor driven wheelchair or mobility scooter (104, figure 5) into a car boot.
